KIM001 K-Cube Piezo Motor Controller

Fig. 6.6 Position Steps Triggering

Example for a move from 0 to 2000 steps and back.
In forward direction: The first trigger pulse occurs at 1000 steps (StartPosFwd), the

next trigger pulse occurs after another 500 steps (PosIntervalFwd), the stage then

moves to 2000 steps.
In reverse direction: The next trigger occurs when the stage gets to 1200 steps.
Note that position triggering can only be used on one TRIG port at a time.

Trig Polarity

The polarity of the trigger pulse is specified in the

Trig. 1 Polarity

and

Trig 2 Polarity

parameters as follows:

Active is High

- The active state of the trigger port is logic HIGH 5V (trigger input

and output on a rising edge).

Active is Low

- The active state of the trigger port is logic LOW 0V (trigger input

and output on a falling edge).

Note

In the

Trig Out Pos. Steps Fwd

mode, the

StartPos. Fwd

value must be reached in

the forward direction for the subsequent trigger sequence to be performed correctly.

StartPos. Fwd

is reached in the reverse direction, the initial trigger will still be

activated, but any subsequent sequence could be corrupted. Similarly,

StartPosRev

must be reached in reverse direction for the sequence to work correctly.
